Reference Design
A2
Charge golden capacitor or battery when VBAT is applied.
3. The width of VBAT trace is recommeded to be more than 2mm.
2. Module drains the maximum current around 1.6A in burst time (577us).
If unused, keep VRTC open.
1. VBAT ranges from 3.3V to 4.6V.
Reference Circuit of ADC
Close to the VBAT pins
Capacitance of C102 should
is recommended here.
be chosen by debugging to ensure
A 5.1V/1W zener diode
Module Design
As only powering the VRTC pin to keep the RTC will lead
an error for about 5 minutes a day, it is recommended
to power VBAT and VRTC pin at the same time when
RTC function is needed.
the max voltage drop during
the burst transmission
does not exceed 400mV.
The voltage range of ADC input channel is from 0 to 2.8V.
Please select a high-precision divider resistance.
4. Capacitance is arranged in ascending order, with the smallest one closing to the VBAT pins,
and all capacitance as close to the VBAT pins as possible.
A Pi match circuit is recommended to be added.
For RF layout, please refer to
RF_Layout_Application_Note.
Don't change those interface for other uses.
